TO all whom it may concern: v

Be it known that I, FRANK F. SNYDER, a citizen of the United States,residing at Torrance, in the county of Los Angeles and State ofCalifornia, have invented certain new and useful Improvements in a BeltSplice, of which the following is a specification.

My invention relates to improvements in a double ply belt-splice forpower transmission machinery, and the objects of my improvements are,first, to provide an un- ,broken running surface in power transmissionbelts of any material, to obtan a 'smooth and endless traction surfaceon pulleys or other fiat surfaces; second, to provide a splice that willmake a permanent and strong joint, by a simple plate and rivet means;third, in a splice that may be applied through the belt that willfurnish the maximum of power transmission without breaking or tearingthe holes or slits therein; fourth, to provide a splice that willconform to the curve of a pulley to increase the traction area of thebelt thereon.

A further object of my invention is to provide a belt-splce that willconform to all the requirements of safety rules and regulations.

A still further object of my invention is to provide a belt-splice thatwill give an equal tension on all parts of the joint, to eliminatetearing, or ultimate wasting of the belt.

A still further object of my invention is to provide a belt-splice thatmay be used with a low cost, simple to install, and inexpensive tomaintain.

I attain these objects by the joint illustrated in the accompanyingdrawing, in which- Figure l represents a plan view of the belt-splice;Fig. 2, a side view of the belt splice; Fig. 3, a sectional view on line3-3 of Fig. l; and Fig. 4 a pin before riveting.

Similar numerals refer to similar parts throughout the several views.

The two ends of the double ply belt 1 are positioned squarely togetherat the joint 6, the slits 7 are cut in the central-end portions of thebelt 1, between the plies thereof, from the joint 6 and extending back asufficent distance to receive a plate 2, the said plate 2 is positionedin two slits 7 with an equal depth from the said joint 6, with thesides'8 on the plate 2 standing back of the sides 9 on the belt l. Theshoulders 4 are integral with oneor both 'sides of the plate 2, theholes 11 pass through the said shoulin the said plate 2, and the pins 3t aren turn po'sitionedthrough the belt 1,

the heads 5 are integral with the said pins 3 and are positioned on thetwo ends thereof, fiush with the outside faces of the belt 1.

The plate 2 is made rigid and is curved to conform to the shape of theface of the pulley over which the belt l runs.

The points 12 are formed on one end of the pins 3, as shown in F igure4, before riveting over the heads 5 to locate and drive the pins 3through the holes ll.

To splice a belt with a plate 2 and pins 3, the two ends of the belt lform the joint 6 which is cut perfectly square, the slits 7 are then cutinto the two ends of the belt 1, to accommodate one half of the plate 2in each of the said ends. The shoulders 4 are formed on the plate 2 innumber and location to suit the requirements, with the holes ll passingthrough the center thereof, to receive and reinforce the said pins 3.The' two ends of the belt l are punched with holes ll to correspond withthe number and location of the holes ll in the plate 2, the plate 2 maythen be placed into position in the slits 7, with the shoulders 4passing into the holes 11 in the said belt 1, the points 12 of the pins3 are then forced through the said holes 11 in the belt 1, and throughthe holes 11 in the shoulders 4, and the entire assembly is then pressedinto a solid joint, by riveting the ends of the pins 3 back into thebelt 1 to form the heads 5, flush with the outer faces thereof, to makean even and unbroken running surface on all four sides of the saidbelt-splice, and a continuous traction surface, with no clearancerequirements other than the actual thickness or width of the said belt1.

'The belt l with the curved plate 2 therein is then run over thepulleys, as shown in Figure 2, and in a straight line, as shown inFigure 3, without bending and the shoulders 4 prevent creeping of thebelt l and shearing of the pins 3, and after continuous running on thepulleys in tension, the belt 1, shoulders 4 and heads 5, will press andwear into a solid unbreakable joint.

A belt with my improved belt-splice can be shifted from one pulley tothe other with no danger to the operator due to sur-plus materialextendng beyond the thickness or width of the belt, `and will runpractioally endless with no pounding or Vbration whatsoever,particularly over small pulleys.

Having thus described my invention what I claim is: y

1. In a belt of the class described, a' belt spliee with two ends joinedtogether, ?in combnation with a curvel plate splieed between the twoends of .the said belt, pins positioned through the said two fitted endsof the belt and the plate, riveted heads inte al wthboth outer erdsofthe said pns ush wthrthe .outer surface of the belt, shoilderepositoned on .the :said plate and eitendig into the said belt-spliceadapted to receive the said pine, as set forth.

In a -do' ble plyfhelt of the elazss described, a belt-splce with twofitted ends joined together, in combination with a ourvetl platepostime& between the ples of the said splice, shoulders positoned in thes'cd'ourved plates, pins positioned through the ends ,ofthe saidbelt andthe said shoulders, r'vet 'h's'integral with the two outer ends of thesaid pns, adapted to lie flush with the outer urfa 'e .of the belt, asset forth.

In testimoy where& 11 .afi my sigature.

FRANK SNYDER.
